To all whom it may concern:

Be it knownthat I, JOHN LALLY, a of the United States, residing atBoston, Sufiolk County, Massachusetts, have invented certain new anduseful" Improvements in Building Columns,- of which the following is aspecification I M invention relates to improvements in buil ing columnsprimarily intended for use in fire-proof or semi-fireproof buildings andit is my object to produce a column with body being filled withplastiematerial, like concrete, which aids in binding the metal partstogether and in which afewsimple,

cheaply made! parts will be united into a structure of great weightcarrying capacity.

and rigidity. A further object is to so utilize the sandwich platebetween super mposed coluinns that it not only firmly unites the columnsbut also strengthens and stiflens the connection between the floor beamsand tie plates.

the floor beams attached; Fig. 2 a sectional view othe structure of Fig.1 on the line 2-2 thereof; Fig. 3 a front view, partly in section, of acolumn with amodified form of connection with the column above it; andFig. 4 a view, partly in section, of a column having but one beamconnected thereto.

As most columns have four floor beams f w secured thereto .1 have chosenthis form for illustration in Figs. 1, 2 and 3. The column comprises acasing 1 enerally made of steel tubing or cast iron. lots 2. 2 are cutin thecasing at the points where the tie plates are to be attached.

In the form shown in Figs. 1, 2 and 3 a long tie plate 3 extends throughopgplsefd the other slots until they abut against the first tie plate,but with their ends outside the casing. The tie plates 3, 4 and 5 areunited at their junction inside the casing, two methods which ma 'beused. T e assembled column is t en filled with plastic material, likeconcrete, which not only strengthens it and makes it fire resistant, butalso helps to unite the arts.

SerialNo. 600,883. I I Y I This sandwich plate extends over" beyond the casingend.. The floor beams or girders 10, 11, 12 and 13 have'their sides orwebs secured to the tie plates 3, 4 and 5. with their tops, or upperflange, abutting against the under side of the sandwich plate 9 which isriveted or otherwise secured to the beams thereby holding the twocolumns and floor beams solidly in position and uniting the two columns.

In the form shown in Fig. '3 the connection between the up er column 14and the lower column is ma e by securing plates 15 and 16 to the'casingends by rods 17, 18 and '19, 20 passing through the plates and beingembedded in the plastic filling. The plates are then secured together attheirouter port1ons.

- In Fig. 4 I have shown a method of at- I taching a single floor beamto a column. The casing 21 has a slot 22 cut therein and a tie plate 23is inserted in the slot, partly within and partly without the casing,being held in place by the plastic filling. The sandwich plate 24extends along the top of the floor beam 25 which is securedthereto whileits web is secured to the tie plate 23.

It is to be'noted that in the type of column I disclosed in thisapplication I have dispensed with brackets on which the floor cams restand have depended entirely upon tie palates extending from the column tocarry e load, using an extended sandwich plate to aid in securing thecolumns and beams together. As these beams and tie plates are generallyentirely within the floor.

structure in fireproof buildings the columns 1 appear cylindrical fromfloor to'ceiling and thereare no brackets orbases to take up space ordetract from the appearance of the building.

I cla1m:

i 1. A'building column comprising a casing J provided with slots, tieplates adapted to engage floor'beams in said slots with their innerportions abutting within the. casing and means for securing the abuttingportions to ether. f

2. A uilding column comprising a casing provided withslots, a tie plateadapted to enga a floor beam extending through oppose -slots, tie,pieces adapted. to engage floor beams extending through the other slotswith their inner ends abutting the first tie plate within the casing andmeans for securing the I abutting portions of the tie plates together.

3. A building column comprising a casing provided with slots, tie platesadapted to engage floor beams in said slots with their inner portionsabutting within the casing and angle pieces secured to the meeting facesof the tie plates whereby they are united.

4. A building column comprising a. casing provided with a slot, a tieplate adapted to engage a floor beam in said slot and secured inposition, a sandwich plate on the end ofthe casing and extendin beyondthe same and adapted to be secure to the top face of a floor beam.

5. Building construction comprising a column composed of a casing, tieplates on said casing adapted to engage floor beams, a superimposedcolumn, a sandwich plate secured to the bottom of the upper casing andextending beyond the same and adapted to engage the top face of a floorbeam.

' In testimony whereof I have hereunto subscribed my name.

JOHN LALLY.
